PROV-O plan?

PROV-O (via prov-wg),

I apologize for leaving before we finished today's telecon [1].

As I look through the notes, I'm concerned about the statement:

"+1 to focus more on ontology first - avoid wasted time on writing lots of documentation we then disagree on :) +1 (Daniel)"

I'm concerned that focusing on "just" some OWL assertions will inhibit our progress.
It is easier to agree upon things that are written down, with examples, and described from the perspectives of PROV-DM, RDF, and OWL.
Any addition to the PROV-O ontology needs some discussion accompanying it, so that the PROV-O team (and others) can be convinced that it is a proper model. 

For example, the qualified involvements proposal [2] seemed to catalyze the use of QualifiedInvolvements by prov-wg.
After months of discussions, it unified the two competing approaches that were never written down.
Unfortunately, no form of [2] is part of the official PROV-O discussion document [3].

The Accounts proposal [4] hasn't been as catalyzing, but at least we can monitor its progress.

As for concrete examples, [5] has not seen any prov-wg adoption for collecting PROV-O examples in our hg repository [6].

Further, when it _does_ come to the OWL assertions, my attempt to decompose the problem into smaller, manageable, ACTION-able pieces [6,7] has also been disregarded in favor of the traditional monolith [8] that nobody seems to want to touch.

Since I've exhausted my approaches to contributing, I'm left with nothing but a question:

       How do you want me to help make progress?
